HENRY FREDERICK, OF BUTLER, PENNSYLVANIA.

IMPRQVEMENT IN AXLE$ FOR VEHICLES.

Specification forming part of Letters Patent No. 145,165, dated December2, 1873, application filed July 12, 1873.

To all whom it may concern:

Be it known that I, HENRY FREDERICK, of Butler, in the county of Butlerand State of Pennsylvania, have invented a new and Valuable Improvementin Wagon Axles and Skeins; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings maing a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of a sectional View of mywagon-axle. Fig. 2 is an under View of the same.

This invention has relation to axles and skeins; and it consists incasting within the metal of the skein the wrought-iron spindlecore,recessed or forged thinner on its under side, and in the lower or underside of the same eastin g a steel rib, whereby the wear of the skein isdiminished. The object of the present invention is to strengthen theconnection between the skein and axle-core, and to render the skein moredurable in respect of wear.

In the accompanying drawings, the letter A designates the end orspindle-core of the wrought-iron axle B. This spindle core is forgedthinner 0r recessed at a on the under side. 0 indicates a strip of steelhaving rivetholes at c c. The skein D is of cast metal. This is castaround the spindle end A, which is placed in the mold. In the samemanner the strip 0 of steel is laid in the mold, and the metal of theskein is cast about it, and about the inner ends of the rivets (I, thussecuring it solidly and firmly in the under side of the skein. Eindicates an extension or flange at the rear end of the skein, behindits collar F,

designed to support the wrought-iron axle at this point, where it isusually secured to the wooden upper axle by a suitable clip,'e. Gindicates the nut, which engages with a thread formed on the projectingend h of the spindlecore, which extends beyond the casting D. In thismanner the skein is firmly secured to the axle-core.

All the advantage of the wrought iron spindle in preventing fracture isobtained, with the harder wearing-surface of the cast metal. Thesuperior rigidity of' the cast-metal skein enables it to keep its formagainst accident, and the resistance to the wea of the wheel is stillfurther increased by the inlaid steel strip on the under side of theskein, which serves to sustain the main portion of the pressure andconsequent friction in the rotation of the wheelhub.

The diminishing of the cast metal at the seat of the steel strip iscompensated by the fullness 2 which fills the recess a in the under sideof the spindle-core. This formation, while strengthening and bracing theparts, also prevents both longitudinal and rotary movement of the castmetal on the core.

That I claim as new, and desire to secure by Letters Patent, is-

The recessed wrought spindle A, in combination with the east sleeve Dand steel plate 0, as specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

HENRY FREDERICK.
